With even more than all due respect to K&R, I cannot recognise either the above text or the previous "game of life" example as being from K&R. Could Alla provide a page reference for both of these, and explain what she meant by her claim that "K&R was published in 1999"? If there was a third edition of K&R published in that year, I'd have thought it would have attracted sufficient attention from the C community that more of us would have heard of it. <snip> -- Richard Heathfield Email: rjh at cpax dot org dot uk "Usenet is a strange place" - dmr 29 July 1999 Sig line 4 vacant - apply within
